The present study was carried out to find the influence of some organic materials on the optimum biomass production of Chrysopogon zizanioides (L.) Roberty (Vetiver) using soil (S), vermicompost (VC), cow dung (CD) and coir pith (CP) at different ratios. The final day results showed that the ideal combination for the growth of the Vetiver is 1:1:1:1 v/v ratio of VC/CD/CP/S. The pH, electrical conductivity (EC), nitrogen (N)- phosphorus (P)- potassium (K), organic carbon (OC), and carbon (C)/N ratio showed in 1:1:1:1 v/v ratio of (VC/CD/CP/S), on 120th day were 7.3, 0.38 dS m ⁻¹, 1.36%, 0.11%, 8.7%, 20.5% and C/N ratio is 15:1. The root and shoot length, fresh weight, dry weight, number of culms, and total chlorophyll content of Chrysopogon zizanioides were 65cm, 197 cm, 312 g, 104.4 g, 36 culms/plant and 40.57 mg/g at 1:1:1:1 v/v ratio of (VC/CD/CP/S) treatment and compared to control sets, the increasing ratio were 6:1, 3:1, 12:1, 12:1, 3:1, 2:1 respectively.
